ZZ'ZZZZZZA "ju- "WQ" L Einf* water in the lower portion a of said chamber i passes into the trough z beneath, the chamber tends to over-balance or tilt around said spindle al and after' the upper portion of the chamber has partly or nearly filled does tilt so that the upper portion of the chamber becomes the lower and vice-versa, The lower y and full portion is immediately cut off from communication with the interior of the hollow spindleA and with the vacuum or vapor space ofthe 'vessel or system being drained and put mto communication with the atmosi phere, whilethe upper and empty portion .is

' i space of the vessel being drained.

'c ut 01T from communication with the'atmosphere-and put into communication with the hollow spindle and the vacuum or vapor When the Water collecting chamber is placed'in the mid-way position, with neither end within the trough z', all the ports in the sleeveJ and hollow spindle are closed. The disliarge valves canl then be cleaned or otherwin@ attended to. When the said chamber isragain tilted, the trapv re-commences to i work.

To prevent a too-ready movement of the i liquid collecting chamber before sufficient i' liquid has accumulated in the upper portion thereof and to prevent the-said chamber balancing in' a midway position, I provide a .weight r which opposes the downward movement of the upper end'of the said chamber. When, however, the said end of the chamber is sufficiently filled with water to over-balance the weight, the chamber tilts and the eliect of the weight is gradually neutralized; inajlly the weight acts to accelerate the movement of the chamber.

' When the apparatus is working-under low pressure conditions, I may make the discharge valvese, f of the type shown" at Fig. 3 where the valve stems are of the same diameter as the valves, to neutralize thel effect of the pressure within the trap upon the valves. 1 By this means I obviate thefheces'sity-for a heavy weight for maintaining the valve in its closed position and also prrvent any disturbance of the action of the trap due to the saidl weight at one end of vthe trap being supported byv the trough,

while the welght at the other end is borne by the lraised .ichamber.

portion of the collecting By the employment of my invention, I

l provide for a practically continuous discharge -of'thewater-of condensation or like j liquid content of the vessel or system being drained vand further, as the whole of the Wear due to the relative movements of sleeve and hollow spindle is at the upper portion of the latter where the ports-are situated and where the weight of the collecting chamber insures a tight joint between the sleeve and spindle, leakage at the ports is reduced to a minimum.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is l. A combined steam and vacuum trap comprising a collecting chamber formed from two independent and equal compartments having a division wall between them, a hol' low spindle passing through the center of the division wall and around which said liquid collecting chamber oscillates, said spindle having ports which alternately place each compartment .of said chamber?, into communication with the liquid space ofithe system being drained, saidl spindle also having ports for placing thesteamjspace of the system being drained alternatelynto communication with thel vextreme up'pei` end of each compartment of said chamber said spindle also/havingotlier ports for. alternately placing each compartment in communication with the atmosphere, all of said ports being controlled by the movements of said chamber, and discharge valves onthe face of each compartment.

2. A combined steam'and vacuum trap comprising in combination, a liquid collect- -ing chamber formed from two independent compartments, a hollow spindle disposed between said compartments and around which said liquid collecting chamber oscillates, ports in said spindle, alternately placing each compartment of said chamber simultaneously in communication both with the liquid and with the steam spaces of 'the-system being drained, other ports in said spindle alternately placing each compartment in communication with the atmosphere, all of said ports being controlled by the movements of the chamber, a trough beneath said chamber, and discharge valves on the face of each compartment alternately discharging into said trough.

" 3. A combined steam and vacuum trap comprising in combination, a li-quid collecting chamber formed from two independent compartments, a Vhollow spindle 'passing through lthe division between saidlcompartments -and around which said liquid collecting chamber oscillates, ports in vsaid spindle alternately placing each compartment of said chamber simultaneously in communication both with the liquid and with the steam spaces of the system being drained, other ports in said spindle alternately placing each compartment in communication withlthe ,atmospher all-of said ports being controlled byy themovements of the chamber,

a trough beneath said chamber supporting saidhollow spindle, discharge valves on the face of each, compartment positively operated by said trough and alielna-tey discharging therento, an arm Carried by the 'Wall of said chamber at a point between said. col'nparments and an ustabe Weight upon said m, as set forth.

In testimony whereof I have boemto set JOHN EDWARD LEWIS OGDEN.
